Abstract: ABSTRACT         A lubricating system of an internal combustion engine is equipped with intake and exhaust valves and a valve operating mechanism having rotating portions and reciprocating portions.       The rotating portions are connected to an oil pump via a first oil path and the reciprocating portions are also connected to the oil pump via a second oil path.  The rotating portions have a cam shaft in operative connection with a crank shaft.  The reciprocat-ing portions include a rocker follower pivoted to a follower shaft and engaging the cam shaft, a rocker arm pivoted to a rocker shaft and operatively connected to the intake or exhaust valve, and a push-rod connecting the rocker follower and rocker arm.  A series feed oil path is defined in the follower shaft, rocker follower, push-rod, rocker arm and rocker shaft so as to pass through their mutual contact portions, and communicates with the oil pump via the second oil path.  Accordingly, in this construction the mutual contact portions between the rotating portions and the reciprocating portions can effectively be lubricated by one lubricating system.

Abstract: ABSTRACT OF THE DISCLOSURE In apparatus for applying pieces of fabric to manufactured articles of tubular shape, and especially to panty hose, a photoelectric cell is employed to reveal the presence of the manufactured article on its stand and to bring the fabric close to the article in the corresponding station only if the article is present on its stand.  In order to have both the fabric and the article rotated, in the corresponding clipping station, by an angle greater than 360°, so that one border of the fabric reaches, in the following sewing station, a position different from the position of arrival at the said clipping station, a device is used that controls the rotation of the stand supporting the manufactured article.  Such a device can be, for instance, a reader provided with a programmed memory so that the readout from a graduated cylindrical scale is stored in the memory and, as soon as the rotation is completed by the amount stored in the memory, the said device arrests the rotation of the stand.  In order to have both the fabric and the manufactured article rotated, at the sewing station, by an angle greater than 360° so that the seam is made, without discontinuity, along the entire border of the article, another device, similar to the previous one, is used.

Abstract: Minor Element Additions to Single Crystals For Improved Oxidation Resistance Abstract The additions of minor additions of hafnium and silicon and mixtures thereof to nickel base superalloy single crystal articles provide significantly improved oxidation resistance.  The oxidation resistance is im-proved both for the case of uncoated articles and in the case where a protective coating such as for example, a MCrAlY coating is present.  For example the addition of .1% hafnium is observed to improve the oxidation re-sistance by a factor of 4 at 2100°F and a similar ad-dition improved the coated  oxidation resistance by a factor of about 2.5 at 2150°F.

Abstract: ABSTRACT:      For the shelling of crustaceans, e.g. shrimps or krill, the preboiled crustaceans are reheated at short duration to a temperature, at which the body liquid just inside the shells is slightly below the boiling temperature, whereafter the crustaceans are subjected to a sudden pressure drop, such that the liquid just inside the shell boils up. With the shells thus loosened the crustaceans are caused to be moved rapidly against the surface of a water bath, whereby the loosened shells are drawn of the bodies. The product in the water bath is separated, and partly shelled crustaceans may be recirculated for renewed treatment.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a photodiode made from materials from group III-V, whose detection effect by photon absorption is amplified by an avalanche, which occurs in a layer separate from the absorption layer.       In order to obtain a low amplification noise, it is necessary that the ionization coefficients differ significantly for the electrons and the holes, i.e. the electric field is weak. This field must be exercised over a considerable length to obtain a high gain. The diode according to the invention comprises a substrate, an absorption layer, a field decrease layer, an avalanche layer, all having the same conductivity type, as well as a contact layer with the opposite conductivity type. The field reducing layer and the avalanche layer both satisfy the condition "concentration x length = constant".       Application to photodetecting diodes in telecommunications by optical fibres.            (Fig 2).

Abstract: ABSTRACT A signal transmission system features a transmitting station which includes an encoder for sampling an analog audio signal or a difference between an analog audio signal and a comparison signal to convert it into a digital audio signal, which is represented by n bits (n ? 2) for one sampling. The digital audio signal is processed by a multi-level former into a signal having 2n different levels and this signal is transmitted after modulation. At a receiving terminal, the 2n-level signal is demodulated and converted by a level discriminator into the digital audio signal.  The digital audio signal is applied to a decoder to reproduce an analog audio signal.  The system requires no frame sync signal and, thereby, enables audio information to be transmitted with a 100% efficiency, which offers the reproduced audio signal with desirable quality.  Provision of parallel-to-serial and serial-to-parallel converters is unnecessary and, in addition, the receiving terminal does not require a frame sync signal reproducing circuit since it needs a clock signal only. This simplifies construction and facilitates completion of the synchronizing system and, accordingly achieves improvements both in performance and in economy.
